Asphalt pavements are a valuable investment for any commercial or industrial property. To maintain their longevity and appearance ,it is crucial to keep them in good condition. One of the most important aspectsof this is ensuring the proper sealing of the surface. This is where our asphalt sealcoating services come in.
Sealcoating is the process of applying a protective coatingto the surface of asphalt to seal and protect it from the elements. The coatingis typically made of asphalt emulsion, which is a mixture of asphalt, water,and emulsifiers or coal tar emulsion.
Cleaning and Preparing the Surface for Sealcoating
Before sealcoating can be applied, the surface must be thoroughly cleaned and prepared. This includes removing all dirt, debris, and oil stains(or applying an oil stain treatment). This helps to remove any contaminantsthat could impact the adhesion of the sealcoat material.
Application Process of Sealcoating
Once the surface is clean, it is ready for the sealcoatingmaterial to be applied. This is done using a commercial-grade sprayer or asqueegee machine. The sealcoat material is applied in a thin and even layer ,making sure to cover all areas of the surface. The goal is to create an even, consistent layer that provides a protective barrier against the elements.
Curing Details
The curing process is crucial for the success of thesealcoating job. The curing time varies based on factors such as temperature andhumidity. In general, the sealcoat material will begin to cure within 24 hoursof application. It is essential to keep traffic off of the surface during thecuring process to ensure that the material is able to fully cure and bond withthe asphalt surface. Duramax usually approaches sealcoating projects in aphased approach for purposes of traffic mitigation.
It is recommended that the surface be kept free of water andother contaminants during the curing process. This can be done by usingbarricades and signage to direct traffic away from the surface or by coveringthe surface with a curing agent that helps to speed up the curing process. Oncethe material is fully cured, it will provide a durable and long-lastingprotective barrier for the asphalt surface.
Other Types of Sealcoat
Coal tar emulsion is a type of liquid asphalt material thatis made by emulsifying coal tar, a byproduct of the steel industry, in water.It is commonly used as a sealant for asphalt surfaces, as it provides aprotective barrier against the elements and helps to extend the lifespan of thesurface.
In recent years, there has been some concern about the useof coal tar emulsion due to its potential environmental and health impacts.Coal tar is a known carcinogen, and exposure to it has been linked to a rangeof health problems, including skin irritation, respiratory issues, and cancer.As a result, there have been calls to restrict or ban the use of coal taremulsion in some areas.
Despite these concerns, coal tar emulsion is still used insome parts of the world as a sealant for asphalt surfaces. In the UnitedStates, for example, coal tar emulsion is still widely used and is considered asafe and effective option for asphalt maintenance. However, alternativesealants made from asphalt emulsion or other materials are also available andare increasingly being used as an alternative to coal tar emulsion.
Overall, the use of coal tar emulsion as a sealant forasphalt surfaces is a complex issue, and the decision to use it should be basedon a careful consideration of the potential environmental and health impacts,as well as the effectiveness of alternative sealants.
There are several reasons why you should sealcoat yourasphalt:
1.Protection: Sealcoating provides a barrier between the asphaltand the environment, protecting it from the sun's UV rays, water, and otherelements that can cause it to break down and deteriorate.
2.Extension of lifespan: Sealcoating can help to extend thelifespan of an asphalt surface by preventing or delaying the need for costlyrepairs and replacements.
3.Cost savings: Sealcoating can be more cost-effective thancomplete asphalt replacement, as it helps to preserve the existing surface andavoid the need for more extensive repairs.
4.Enhanced appearance: Sealcoating can improve theappearance of an asphalt surface by filling in small cracks and giving it afresh, black appearance.
5.Increased property value: A well-maintained and attractiveasphalt surface can increase the value of your property.
Overall, sealcoating is an important part of maintaining andpreserving the condition of asphalt surfaces. By investing in regularsealcoating, you can ensure that your asphalt surfaces remain safe, functional,and attractive for years to come.Contact us today to schedule a consultationand learn more about our asphalt sealcoating services.
